1.拼接式刀柄如图1所示,刀柄与刀夹主要靠端面定位,并通过锥头螺钉的锥面作用,使刀柄与刀夹成为一体。同一刀柄可以用于拼接各种不同的刀夹。因此,有利于实现标准化、系列化和通用化。 2.两接触面式短锥柄因受刀架尺寸所限,中小型NC车床ATC刀柄须小型化,通常认为采用短锥柄最为合适。但是,一般的短锥柄会因接触面过短而刚度不足。图2所示短锥柄,除锥面接触外,端面也接触。这样,既能保证足够的刚性,也具有较小的体积。 3.弹性钻夹头
1 stitching knife handle shown in Figure 1, the knife handle and knife clip mainly by the end positioning, and through the cone head screw cone effect, so that the handle and the knife into one. The same shank can be used to stitch a variety of different tool holders. Therefore, it is conducive to standardization, serialization and generalization. 2. The contact surface of the short taper shank limited by the size of the knife, ATC ATC small and medium-sized NC lathe to be miniaturized, usually considered the most suitable short taper shank. However, the general short taper shank will not be stiff due to the short contact area. Figure 2 shows the short taper shank, in addition to taper contact, the end surface is also in contact. In this way, both to ensure adequate rigidity, but also has a smaller volume. 3. Flexible drill chuck
